Hi everybody.
I have a HUNTLEIGH BD4000 Fetal Monitor.
All functions of this machine are ok but when active printing, pape is driven but nothing print out. I think print head alignment faults but I'm not sure.
If anyone have experience of this machine, please give me advice.
Thanks and goodluck.

Thermal paper only print on one side, miss look sometimes that we have loaded the paper the other way around. If you have dissassembled the unit, check for lose connectors, ground cable of thermal head if not connected sometimes cause failure of printing. and two other possibilities you might have a defective thermal head or board, if you have a known good thermal head, you could try if it prints...

Thanks for your advice.
